BUN`G-.VALVE FOR BARRELS.

SPECIFICATION forming part of Letters PatentNo. 288,390, `dated November13, 1883.

Applicationl tiled April 4, 1883. (No model.) l l To all whom it mayconcern,- Be it known that we, ALONZO E. WITHER- ELL, of Medford, inthecounty of Middlesex, in the State of Massachusetts, and DANIEL B. 5CLEMENT, of Boston, inthe county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Bung- Valves forBarrels, of which the following, taken in connection with theaccompanying drawings, is a specication. H

Our invention relates to a and` valve for use in beer and other barrels;and it consists in the combination, with a bung having a centraldischarge-orice, of a valve arranged to close the inner end of saidorifice and to open inward, athreaded valve-stem, and a socketed nut setin said bung and adapted to be revolved therein and force said valve inward or outward, as will be more fully de- It further consists in anovel arrangement of the valve and valve-stemrelative to thedischarge-orice, whereby the valve is adapted to close thedischarge-orifice and the opening in `which is mounted thevalve-stem,`as will be described.- Y

Figure 1 of the drawings isa front elevation of our improved bung andvalve. r Fig. 2 is a section Online `0c .1: on Fig.`l; and Fig. 3 is asimilar section, illustrating a modification in the position of thevalve and valve-stem.

A is the bung, provided with the flange a, to bear against the outersurface of theA barrelhead, and with the central `discharge-oriiice, b.

A conical valve-seat, c, is formed in the in- `nerend ofthe bung A. uponwhich is seated the valve B, attached tothe inner end of the valvestemd, the outer end of which has formed thereon a male screw-thread, to fita corre- 4o spending female thread in the cylindrical nut e, fitted tobe revolved in abearing in the bung, between the shoulder c and theinner end ofthe hanged annular plate or ring f, firmly secured by screwsto the front end of the bung, as shown.

The outer end` of the nut chas formed therein a key-socket,` e2, for thereception of a suity able instrument, by means of which it mayberevolved in either direction, Vaccording as to 5o whether it is desiredto open or close the valve.

combined Abung The inner end of the bung may be parallel with its outerend, and the valve-stem be bent, as shown in Fig. 3; or the inner end ofthe bung may be inclined or oblique to its outer end, and a straightvalvestem arranged at an-A angle to the discharge-orifice may be used,as shown in Fig. 2; but we prefer the latter form, for the reason thatthe valve eiifectuallyy closes both the discharge-orifice and theopening in which the valvestem and nut have their bear- 6o ings, andthus obviates the necessity for a stuffing-box or packing around the"valve-stem. This makes a very convenient and effective device fordrawing beer and other liquids from barrels, and which may be applied tothe barrels when they are made, and remain therein till the barrels areworn out without danger 0f the valve being opened in handling thebarrels.

The outer end of the discharge-orice is 7o provided with a screwthread,to receive a discharge-pipe or faucet.

by LettersPatent of the United States, is
